Product details
Overview
SMB10J36AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 1000 W peak pulse power (10/1000 µs), 36 V stand-off voltage (VWM), and 58.1 V clamping voltage (VC) at 17.2 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines and power rails against inductive switching transients.
For engineers reviewing the SMB10J36AHM3_A/I datasheet, SMB10J36AHM3_A/I pinout, SMB10J36AHM3_A/I application, or SMB10J36AHM3_A/I equivalent, this part delivers verified automotive-grade transient suppression with halogen-free RoHS compliance, MSL Level 1 rating, and validated clamping performance under 10/1000 µs surge conditions.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds 36 V (VWM), it avalanches to clamp transients at ≤58.1 V while diverting up to 17.2 A (IPPM) without damage. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 µA at VWM).
Designed for surface-mount placement on PCBs with 0.2" × 0.2" copper pads per terminal, it achieves thermal resistance of 72 °C/W (junction-to-ambient) and supports continuous operation from –55 °C to +150 °C junction temperature, meeting automotive reliability requirements per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 40.0 V / 44.2 V at 1.0 mA - guaranteed avalanche initiation window for predictable turn-on |
| VC @ IPPM | 58.1 V at 17.2 A - clamping voltage under full 1000 W surge, limiting downstream stress |
| PPPM | 1000 W (10/1000 µs) - peak surge energy handling capacity for automotive load-dump immunity |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves signal integrity in high-impedance sensor interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB10J36AHM3_A/H | Same electrical specs and AEC-Q101 qualification; differs only in tape-and-reel packaging (750-unit vs. 3200-unit reel) | No functional difference; selected based on production volume and SMT line feeder compatibility | Choose HM3_A/H for low-volume prototyping or small-batch assembly where reel size impacts changeover frequency |
| SMBJ36AHE3_A/I | Lower PPPM (600 W), higher ID (5.0 µA), same VWM/VC but not AEC-Q101 qualified; uses E3 (non-halogen-free) material | Limited to commercial-grade industrial or consumer applications; unsuitable for automotive Tier-1 BOMs | Select only if cost sensitivity outweighs automotive qualification and halogen-free requirements |
Compared with SMB10J36AHM3_A/I, the HM3_A/H offers identical protection performance in smaller reels for flexibility, while SMBJ36AHE3_A/I trades surge robustness and automotive compliance for lower unit cost in non-automotive designs.

FAQ
What is the clamping voltage of SMB10J36AHM3_A/I at its rated peak pulse current?
The SMB10J36AHM3_A/I has a maximum clamping voltage (VC) of 58.1 V when subjected to its rated peak pulse current (IPPM) of 17.2 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream ICs connected to the protected line.
Is SMB10J36AHM3_A/I suitable for automotive applications?
Yes, SMB10J36AHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction. It meets automotive requirements for temperature cycling, high-temperature operating life, and mechanical robustness-making it appropriate for engine control units, ADAS sensors, and body electronics where reliability is critical.
What does the "_A/I" suffix mean in SMB10J36AHM3_A/I?
The "_A/I" suffix in SMB10J36AHM3_A/I denotes the revision code ("A") and packaging format ("I" = 13-inch diameter tape-and-reel, 3200 units per reel). This matches Vishay's ordering convention where "I" specifies the large-reel configuration optimized for high-volume SMT production lines.
How does SMB10J36AHM3_A/I differ from SMBJ36A variants?
SMB10J36AHM3_A/I delivers 1000 W peak pulse power (vs. 600 W for SMBJ36A), lower leakage (<1.0 µA vs. 5.0 µA), and AEC-Q101 qualification-while sharing the same 36 V VWM and SMB package. These differences make SMB10J36AHM3_A/I suitable for demanding automotive surge immunity, whereas SMBJ36A targets commercial-grade applications.
What is the thermal resistance of SMB10J36AHM3_A/I in standard mounting conditions?
Under standard JEDEC test conditions (mounted on 0.2" × 0.2" copper pads per terminal), SMB10J36AHM3_A/I exhibits a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W. This value supports reliable operation up to +150 °C junction temperature in thermally constrained automotive PCB layouts.
